FREDERICK PHINNEY, OF NEW YORK, N. Y.

KEYLESS CLOCK.

To all whom it may concern:

Be it known that I, FREDERICK PI-IINNEY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Keyless Clocks, of which the following is a specification.

This invention relates to keyless clocks, in which the spring is wound by means of a turning rim mounted on the clock case and connected by suitable intermediate gearing or devices to the spring.

The present invention is especially an improvement on the clocks shown in U. S. Patents Nos. 967,428 and 967,429.

Existing comn'iercial movements usually have the spring arbor located at one side of the central axis of the clock, and it is desirable to provide means for winding the spring of such a movement by connection to the rim operated devices referred to. In Patent No. 967,428 an annular gear is provided, attached to the rotatable casing. This is objectionable on account of expense and for various other reasons.

By the present invention improved means are provided for operatively connecting the spring to the rotatable casing, utilizing also a central pin or stud which supports the movement in the casing.

The invention is illustrated in the accompanying drawings in which Figure 1 is a central vertical section of the clock. Fig. 2 is a section on the line 2-2 of Fig. 1.

Referring specifically to the drawings, 6 indicates an outer cup shaped casing the base or back of which may be fixed to any suitable support. For automobile use it will be attached to an angular bracket to present the face at the proper angle. This casing has a socket at the back which receives a stud 8 projecting from the inner movement plate 9, the stud being held in position by a screw 10 01' the like accessible through a hole in the wall of the outer casing. Obviously the stud may be fastened to the casing in any other suitable way.

Fitting at a working fit within the outer casing G is an inner cup shaped casing 12 on the front end of which is screwed the wind ing rim 13 which carries a glass 141 and reflector ring 15 as usual.

The back of the inner casing 12 has a squared or other non-circular hole at 18,

through which the stud 8 extends, and fitted in this hole is the squared non-circular end of a collar 19 which is rotatable on the stud 8. Thus the collar will turn when the inner casing 12 is turned. The front end of the collar has mounted thereon a gear 20, which turns with the collar, and this gear meshes with another gear 21 fast on the arbor 22 of the spring 23. The spring arbor has its hearings in the plates 9 and 21 of the movement, and power is communicated from the spring to the movement through the ordinary spring barrel and train which require no particular description, and may 3e of any suitable kind. One end of the spring is fastened to the arbor and the other end to the barrel, as usual.

The clock spring is wound by turning the rim 13. This turns the inner casing 12 and the collar 19, the gears 20 and 21, and the spring arbor, thereby winding the clock. The availability of the casing structure for use with commercial movements is advantageous, and the spur gears required can be produced at less cost than a ring gear and pinion, while at the same time the advantage of supporting the movement rigidly on a central stud is retained.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is 1. In a keyless clock, the combination of a movement, a central stud supporting the same, a casing rotatable around the movement and stud, the movement having a spring the axis of which is eccentric to the stud, and a spur gear mounted to turn around the stud and connected to the casing to turn therewith, and operatively connected to the spring to wind the same.

2. In a keyless clock, the combination of a movement provided with a spring eccentric to the central axis of the movement, a stud at said axis supporting the movement, a casing rotatable around the movement and stud, a collar rotatable on the stud and connected to the casing to turn therewith, and gearing between the collar and the sprin to wind the latter when the collar is turned.

3. In a keyless clock, the combination of a movement provided with a spring and its arbor, central stud supporting the move ment, a casing rotatable around the movement, a collar rotatable on the stud and connected to the casing to turn therewith, a spur gear mounted on the collar, and a spur gear on the spring arbor, meshing with said spur gear.

i. In a keyless clock, the combination of a movement having a back plate with a cen 5 tral supporting stud projecting rearwardly therefrom and a spring eccentric to the stud and mounted in front of the back plate, the

spring arbor extending through said back plate, a casing rotatable around the stud and 10 movement, and gearing between the rear end of the spring arbor and the casing, including a spur gear extending around said stud belnnd the back plate.

In tGStll'DOHY whereof, I allix my signature in presence 0t two witnesses.
